IMPROVEMENT IN SUGAR-GANE MILLS.

'ro ALL WHoM 1r MAY eoNeEnit:

Be it known that I, ORLANDo CLARKE, of Rockford, in the county of Winnebago, and State of Illinois, have invented a new and useful Improvement in Cane-Mills; and I do hereby declare that the folloiving is u. full,- clear, and exact description of the construction and operation of the same, reference being had to theannexed drawings, making a part of this speciication, in which- I Figure 1 represents a front elevation of my cane-mill'.

Figure 2, a vertical section through the same..

Figure 3, a rear elevation thereof; and

'Figure 4 is a view of the scraper showing its ribbed sides. v

It is the object of my invent-ion to support the rollers and driving-gear in a compact frame, under an arrangement that Will prevent the rollers from clogging or the expressed juice from being Wasted; and to this, end my invention consists, rst, in placing the rollers, driving-shaft 'andugearg and reociving=pan for the juice,` in a compact frame that shall constitute the ends of the pan and support the driving-shaft in adjustable bearings; second, in a scraper that shall cleese the roller without obstructing the-escape of the expressed juice.

To carry out/the objects of my invention I construct a metallic frame of two side pieces, A and B, connected at the bottom by cross-braces C and D, secured by screws on the inner sides of the frame, and at top the sides A and B are connected by a strong plate, E, that projects on lone side to give the upper bearing for the driving-shaft F, while this shaft rests in a step, G, at the bottom, supported by a bracket, II,l secured to the side of the frame Bf Thus arranged, and the bearings of the shaft and its step both being adjustable, it is manifest any slight inequalities in the shaft can be readily adjusted to keep it` always truly vertical and the driving-gearin proper coupling rr'th its pinion. Three crushing-rollers, J', K, and L, are journalled in suitable boxes in the frame and arranged in a triangle, and such'a distance apart as to crush the cane eifeetually, the top roller-being stationary, whilethe lower-,rollers are adjustable to permit a varied feed. The top rellerJ carA ries on one journal a-.mitre pinion, M, that receives motion in the direction of the arrow 1 from a mitre drivingd gear, W, on the shaft F, which is driven 4by a sweep properly secured to the plate on its top. The opposite end ofthe top roller J carries a cog-geur, P, that couples with cog gear-wheels Q und R on the projecting journels of rollers K and L, which rotate in the direction of the arrows 2 and 3. Beneath the rollers a pan, AS,lis situated to receive the expressed juice, of'which the sides of the frame constitute the ends, and vfrom which a. trough conveys thejuicc through the sideof the frame to anyrproper receptacle. The sides of the frame are stayed by-screW-bolts 4 and 5 and braces 6, 7, and 8. A mouth-piece or feeding-tube, ',l, receives the cane to guide it between the rollers, and an apron, U, receives the crushed cane or baggasse as it leaves the rollers.v Between the rollersrK and L, and directlyv beneath the roller J, I place a scraper, Y, shown in iig. 4, so con-- structed that one side of the scraper shall rest with a sharp edge against the front roller K and effectually prevent it from clogging, while bars 9, at its back, leave a suicient space for the juice to Iiow between the scraper and roller L without interrupting its oivto the pan. The scraper V also Acarries flanges -10 at itsonds, which pass over the ends of the'rollers-and thus preventit from becoming displaced while the y1nill-\is in operation.

The operation is as follows: Power being applied tothe sweep, the rollers rotate in the direction of the urrovvs, and, receiving the een-e to be crushed through the guide-tube, crush it and pass it over the apron to the ground; while theseaper removes all particles that may adhere to the front roller and keeps it from clogging, the juice from the crushed cane lescapes from the rollers in a. stream to the pan.

Thus constructed and arranged, my cane-mill is compact, strong, and perfectly eiective.

What I claim as my invention, and desire to secure by'Letters Patent, is

, The arrangement, in a cane-mill, substantially as described, of the'frame, the rollers, the feeding-tube, the pan, and the scraper, for the purpose set forth.

In testimony whereof I have hereunto subscribed my name.

ORLANDO CLARKE.
